Answer:
Natural Selection is a process where the weaker species usually dies first.
I would go with letter A.
If there was no competition there would be an overpopulation. If there was limited food its risky and they could possibly be extinct.

Answer:
Blood is composed of several types of cells:
- <u>RED BLOOD CELLS</u>: They are the oxygen carriers of the body i.e. they pick up the oxygen as the blood goes through the lungs & release of oxygen to cells.Also known as erthrocytes
- <u>WHITE BLOOD CELLS</u>: also known as leukocytes.They are the soldiers of the body.Aims at fighting against the infections ( caused by bacteria & virus)
- <u>PLATELETS</u> : helps in the blood clot in response to any wound or injury
There are five types of white blood cells & approx %age they made up in blood are:
•Neutrophils (55% to 70%)
•Band neutrophils (0% to 3%)
•Lymphocytes (20% to 40%)
•Monocytes (2% to 8%)
•Eosinophils (1% to 4%)
•Basophils (0.5% to 1%)
When children are more than 4 year old they have higher % age of lymphocytes than the adults do.
Atomic number = number of proton = 16
Atomic mass = number of proton + number of neutron = 16+18 = 34
Net charge = Number of proton - number of electron = 16-13 = +3
OPTION A IS YOUR ANSWER....
The more paramagnetic the species is, the largest the mass shift is -O2. The more paramagnetic the species is, the larger the mass shift. So, since oxygen has two unpaired electrons in the molecular orbital diagram it will have <span>the strongest mass shift on a magnetic susceptibility balance.</span>
Bird sounds are made in the syrinx, but of course, the air sacs, passageways and the bird's lungs, also contribute to the production of sounds.
When birds start to sing,the 2 passageways between the lung and the syrinx, closes. Then, the sir is squeezed into the air sacs by the chest muscles. Squeezing the air sacs that surrounds the syrinx forces each of the two thin membranes in the syrinx into the 2 passageways between the lung and the syrinx.This process does not allow air to travel through.Afterwhich, muscles around the syrinx contract and tighten one membrane and pulls it out into the passageway (1 of the passageway). Air in that passageway can now move,which passes quickly over the membrane. That fast moving air causes a vibration, thus, sound is produced.
